Andreas Lehmkühler commented on PDFBOX-5009:
--------------------------------------------
[~tilman] Looks good to me, just one small improvement for pdfs consisting of a
lot of pages. To minimize the number of elements within the set, it should be
sufficient to store the page tree nodes:
{code}
if (set.contains(kid))
{
LOG.error("This node has already been visited");
continue;
}
else if (kid.containsKey(COSName.KIDS))
{
set.add(kid);
}
{code}
